<h2>Detailed Description</h2>
<p>The QAbstractFormBuilder class provides a default implementation for classes that create user interfaces at run-time.</p>
<p>QAbstractFormBuilder provides a standard interface and a default implementation for constructing forms from user interface files. It is not intended to be instantiated directly. Use the <a href="qformbuilder.html">QFormBuilder</a> class to create user interfaces from <tt>.ui</tt> files at run-time. For example:</p>
<pre> MyForm::MyForm(QWidget *parent)
     : QWidget(parent)
 {
     QFormBuilder builder;
     QFile file(&quot;:/forms/myWidget.ui&quot;);
     file.open(QFile::ReadOnly);
     QWidget *myWidget = builder.load(&amp;file, this);
     file.close();

     QVBoxLayout *layout = new QVBoxLayout;
     layout-&gt;addWidget(myWidget);
     setLayout(layout);
 }</pre>
<p>To override certain aspects of the form builder's behavior, subclass QAbstractFormBuilder and reimplement the relevant virtual functions:</p>
<ul>
<li><a href="qabstractformbuilder.html#load">load</a>() handles reading of <tt>.ui</tt> format files from arbitrary QIODevices, and construction of widgets from the XML data that they contain.</li>
<li><a href="qabstractformbuilder.html#save">save</a>() handles saving of widget details in <tt>.ui</tt> format to arbitrary QIODevices.</li>
<li><a href="qabstractformbuilder.html#workingDirectory">workingDirectory</a>() and <a href="qabstractformbuilder.html#setWorkingDirectory">setWorkingDirectory</a>() control the directory in which forms are held. The form builder looks for other resources on paths relative to this directory.</li>
</ul>
<p>The <a href="qformbuilder.html">QFormBuilder</a> class is typically used by custom components and applications that embed <i>Qt Designer</i>. Standalone applications that need to dynamically generate user interfaces at run-time use the <a href="quiloader.html">QUiLoader</a>, found in the <a href="qtuitools.html">QtUiTools</a> module.</p>
<p>See also <a href="qtuitools.html">QtUiTools Module</a>.</p>
